Review on Sun Company TempaComp - Ball Compass and Thermometer Carabiner - Outdoor Accessory for Hiking, Backpacking, Camping - Clip On to Backpack, Parka, Jacket by Anthony Jagers

A week later the thermometer and compass failed, they were just hanging on a key hook by the front door. I wasn't going to use it at all for a week and just see if it really falls apart like people say and it does. This is so bad it's even funny. I suspect it gets a star because it actually points in the right direction (if you keep it away from metal) and measures temperature. If you buy one, put super glue on it to hold it together.
